HOW TO REPLACE THROTTLE TRIGGER ON Echo SRM 210 GRASS TRIMMER - YouTube

hello wayne, this is all i could find,hope this helps,,

It is ridiculous, there are a bunch of bolts, and then a multi-fit brochure showing a grid of nonsense.
There are instructions on the inside of the package, however that is how to string the line.

Navigate to your exact model using Echo's public website.
Click the "WEB-PLUS PARTSEARCH" link at the bottom right of their homepage.

Hope this link helps.

I have the same model. Home Depot assembles their trimmers then sells them, so I didn't get the stuff that comes with it. A 3/16" punch works perfectly.

Cut two separate pieces of string, about 7 ft. each.

Stick the end of the line in the hole on the inside of spool.

Wind clockwise onto spool, putting the line that is closest to the ground on first.

Once you have winded this piece on, lock the last 4 inches of line through the slits on spool.

Repeat process for second piece of line, locking the last 4 inches in slot opposite the other locked in piece.

Put the spool on the trimmer, feeding the end of lines through either hole on trimmer.

Before you push the spool all the way on, pull the strings out of the locked position.
